"This stuff has been available for a long, long time."
Yes indeedy.
Ground penetrating radar, for example, has been around since proper Time Team was on proper Channel 4. And that's going back a while. Given the ability of modern DSP systems to recover information from what looks a lot like noise, GPR ought to be quite useful these days. Might need a different skillset than BT Openreach and subbies are used to paying for though.
And as for drilling and trenching, interested readers might want to have a look at e.g. ditchwitch.co.uk for the kind of stuff that the Tracy family and their fans used to dream about.
Even YouTube has a GeoRipper video, dated 2016.
